macfailure - A human being who gets picked on so hard for their last name

A human being who gets picked on so hard for their last name that it’s like they’re the only one who failed the whole test and everyone else passed.

In a DM, someone writes, 'MacFail? You’re the only one who failed the whole test.'

During a game of tag, someone yells, 'MacFail! You’re the worst runner here!'

At the park, a kid says, 'MacFail? That’s the worst name ever!'
